Conductive Graphite Sheets and Bars

A low surface resistivity makes this graphite a good electrical conductor. Since this graphite won't adhere to metal, it can be used to fabricate furnace parts, crucibles, and ingot molds.

Ultra-Conductive Graphene Sheets

This highly conductive graphene material is often used in electronic devices, such as cell phones, laptop computers, digital cameras, and LEDs. It can be folded without tearing or damaging the sheet and can be cut into smaller pieces with scissors. Thickness, width, and length tolerances are not rated.

Ultra-Fine-Grain Conductive Graphite Sheets

This graphite is denser and slightly stronger than standard conductive graphite because it has a smaller grain. A low surface resistivity makes this graphite a good electrical conductor. Since this graphite won't adhere to metal, it can be used to fabricate furnace parts, crucibles, and ingot molds.
